[call for help] to build a later clang-trunk src

[Craig Butler]

Hello Folks

Is there anyone out there with some spare cycles and a fast(ish) sparc64
box ?

I have raised a couple of PR's relating to clang builds on sparc64.  I
am trying to get the latest clang-trunk project built and am hitting
some hurdles.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195934
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194473

Can someone please shadow the work and see if the issues are repeatable.

I am using sparc64 10.1-RELEASE and rebuilding the 10.1-RELEASE src to
give us a clang 3.4 to work with to build the later clang.

To do this you need the following set in /etc/src.conf;
WITH_CLANG= yes
WITH_CLANG_EXTRAS= yes # Build additional clang and llvm tools, such as
bugpoint

once that completes and make installworld is run clang should be
installed.

I am then additionally setting in /etc/src.conf;
WITH_LIBCPLUSPLUS=yes
CC=clang
CXX=clang++
CPP=clang-cpp

Then make  and make install (in order);
/usr/src/lib/libcxxrt
/usr/src/lib/libc++

That should be clang and the c++ library installed ready for building
the clang-trunk.

so I move /usr/src and /usr/obj to .old, mkdir /usr/obj, and then...
svnlite checkout
svn://svn.freebsd.org/base/projects/clang-trunk /usr/src/

then try a make buildworld on the new source....... and that's where it
falls over.

I have had different errors --
On my first run I was getting clobbered with;
/usr/src/lib/libc/../../include/signal.h:84:60: error: expected function
body
       after function declarator
 int     sigwait(const sigset_t * __restrict, int * __restrict)
__nonnull_all;

Second run got clobbered with;
fatal error: 'sys/capsicum.h' file not found

I can get a successful build if I use;
make buildworld SRCCONF=/dev/null __MAKE_CONF=/dev/null

Any help (or repeatable results) would be appreciated.  If anyone spots
any issue please yell!

Not having much luck trying to build with gcc48 either.
